FORREST J. COUCH AND WILLIAM F. WEBBER, OF ROCHESTER, NEW 'EEURK, itrliilllllfhlflltfl TO THE AMERICAN LAUNDRY MACHINE ronarlon or oHIo.

RY CQMPANY, F GINGINNATI, ll-HQ, .3. EUR-- TILTING-TYPE PRESSING-MACHINEQ United States, residing at Rochester, in the county of Monroe andState of New York,'

have invented certain new and useful improvements 1n Tllting-Type Pressing-Machines, of which the following is a specification.

This invention relates to pressing machines and more particularly to what is known as the tilting type press, in which. a lower presser member is so mounted as to have relative movement toward and from an upper stationary presser member and can also be tilted to move laterally away from said stationary member for applying the work thereto and removing it -therefrom.

The object of the invention is to provide an improved press of this type having enshioning means for preventing shock or blow when the movable pressing member is re leased from pressing emragement with the stationary member; wherein the weight of the movable member is in effect counterbalanced to reduce the effort necessary to swing or tilt it forward or to raise it into pressing relation with the stationary member; which is so arranged as to largely prevent breakages of the steam connections or swinging joints; and which is also provided with improved means for guiding the movable bed in its several movements, and for arresting its outward movement by a cushioning action to relieve shock; y

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the drawings, which represent one embodiment of the invention, Figure l is a side elevation; Fig. 2 is a frontview; Fig. 3 vis a horizontal section on the line 3-3, Fig. 1; and Fig. 4 is a sectional elevation on the line l l, Fig.

The machine shown in the drawings comprises a main frame consisting of a base 1 resting on the floor or other support and an upright column 2 whose upper arched end supports the stationary hollow pressing member 3 which may be heated in any suit able manner, as by steam circulated there through from the supply pipe lto the dis char 'e pipe 46% Below the stationary press ng member 5 1s a cooperating movable pressing member 5 carried by a head don the upper end of a Specification of Lettersfatent.

bar or red 7 whose lower end is hinged at 8 to a link 9 pivoted at 10 to the main frame, the bar 7' and the odor swung outwardly or forwardly from the frame to the position shown in dotted lines, Fig. 1. Below the link 9 are two tog gle links 11 connected to the pivot 8 and at 12 to the main frame the lower of said links to forming one arm of an operating lever whose other arm is formed as a foot treadle 13. By pressing down on the foot treadle the toggle is straightened and carried beyond the center lines, Fig. l, and the pressing member 5 forced upwardly into and held in pressing relation with the stationary bed or press ing' member 3.

frame, and which spring is compressed between. said frame and a. clevis 17 on said rod. The swinging press head works between two arms 18 of a guide to thefranie, and having ears 20 to receive studs 21 upon which are journaled the two arms 22 of a yoke-like member 23 embracing the frame and supporting in front thereof a sleeve guide 2i surrounding a rod rod is slidable in said guide and on the rear side thereof carries a compression spring 26 held thereon. by a collar 27, while its forward end is threaded into a elevis 28 pivoted upon a shaft 29 passing throng head 6, and whose ends lie in notches or cess'es 31 of two shoes 32 traveling along the inner faces of the guide arms 18, and which shoes are attached at their upper ends to the lower face movable pressing member 5.

The two shoes engage the surfaces of the guide arms relieving fiat faces head except reetion of its tilt or swing from the main frame Wi li-en the movable I g outwardly, or to the dotted. line position, Fig spring is compressed between the guide 24 and collar 2'? and the in the normal di-- spring and collar form a cushion to limit the no to the lock position shown in full are When the toggle is broken and the press released by depression of the 7 rod 16 connected to member 19 attached said M an ear 30 of the es of the ion and prevent lateral movement toward and away we 'when it is released by ner as the upper bed by in all the different vertical positions of the press head, and the shoes 32 serve as stops to properly locate the presser member 5 under thestationary bed 3, for which purpose their rear ends engage the main frame, as shown in dotted lines, Fig. 1.

Suitable means is also provided for cushioning the downward movement of the pressmg member 5 and counterbalancing the same so as to both prevent the injurious effect of knocks and blows to the mechanism and the steam pipes and also reduce the effort required from the operator. For this purpose there is provided a tension spring 33 having an eye 34: at its lower end held in a hook 35 screwed into the lower end of the bar 7, or a member 36 carried thereby, and at its upper end having an eye 37 caught in a hook 38 screwed into a suitable fixed member, such as a portion of the main frame, or, for example the member 19 attached thereto.

Spring 33 has several distinct functions. First, it counterbalances the weight of the movable press head and its associated parts, thereby relieving the operator of the greater part of the work of lifting such parts in operating the press. For this purpose the eye 37 is threaded into a small head 39 attached to the spring and by adjusting said eye in or out the spring may be in effect shortened or lengthened to vary its tension before attaclr ing it to the hook 38. The spring tension should be almost enough to lift the bed 5 breaking the toggle. This spring, therefore, also serves as a cushion to soften the blow of the descending bed and protects the joints of the mechanism and piping against thecffect of the unavoidable shocks and jars. occurring in the use of machines of this type. Spring 33 is also of such size that it is under slight tension even when the lower head is fully raised. Consequently said spring is effective immediately when the head begins t0 move downward and exerts its retarding effect upon the downward movement of the head throughout its downward movement, gradually arresting it by the increasing tension of the spring. Second, spring 33 is applied to the lower end of the bar 7 behind the pivot 8. It, therefore, always has a. tendency to tilt the bar 7 and press head outwardly around said pivot. By more or less screwing in the hook 35 this tendency may be (lin'ii'nished or increased, as the lever arm varies. Hook 35 is manually adjusted so the bed just balances. requiring little or no effort by the operator to swing it forward for exposing the movable bed.

The lower bed is heated in the same man a steam supply circulated through a cavity or chamber therein. Said steam supply comes from a, pipe 40 on one side of the press eon'nnunicatin by a swivel pipe joint 41, whose axis coincides with that of the pivot 10; with a short pipe 42 leading to a similar swivel pipe joint 43 on the axis of the pivot 8. (hence through a pipe 44 to the hollow bed. The discharge pipe 45 is on the other side of the press and includes swivel pipe joints similar to those just described, the entire arrangement cnabling an uninterrupted steam supply to be circulated through the bed without interfering with its various movements.

The press described may be used for pressing any kind of small work, such as shirt sleeves, yokes, cuffs or the like. and the two pressing members may. of course, be suitably shaped for the particular articles to be pressed. Other modifications within the scope of the appended claims will also readily occur to those skilled in the art.

What We claim is 1 1. A pressing machine, comprising a frame, a stationary pressing bed thereon, a cooperating pressing member having advancing and retracting movement toward and away from said bed and also lateral movement relative thereto, and means for gradually arresting the retracting movement of said member when the press is released, said means also having a. normal tendency to produce lateral movement of said member relative to .aid bed.

2. A pressing machine, comprising a frame, a stationary pressing bed thereon, a cooperating pressing member having advancing and retracting movement toward and away from said bed andalso lateral movement relative thereto, and a single spring connecting said member to a fixed support and servingto graduall arrest its retracting movement and having a tendency to produce lateral movement of said memhers relative to said bed.

3. A pressing machine, comprising a frame, a stationary pressin bed thereon, a cooperating pressing mem )er having advancing and retracting movement relative to said bed and also a. lateral swinging movement around a pivot relative thereto, and a spring connected to said member at one side of said pivot and serving to counterbalance its weight and also produce swinging movement of said member around its pivot.

4. A pressing machine, comprising a frame, a stationary pressing bed thereon, a cooperating pressing member having advancing and retracting movement relative. to said bed and also a lateral swinging movr ment around a pivot relative thereto. a spring connected to said member at one side of said pivot and serving to counterlmlanee its weight and also produce swinging movement of said member around its pivot. and means for varying the distance between said pivot and the location of the point of connection of said spring to said member.
